As an excellent insulating material, flexible polyimide films possess good electrical insulation, high-temperature resistance, corrosion resistance, and strong mechanical strength. Therefore, they are widely used in the manufacturing process of high-end electronic devices, especially in the manufacturing of high-frequency circuits and multilayer circuit boards, where the multilayer composite process of flexible polyimide films is crucial.

[0003] Currently, the composite processing of flexible polyimide films mainly involves bonding different types of composite films in multiple layers through methods such as pressure and heat treatment. Existing composite equipment typically includes multiple composite film rolls, heating rollers, pressure rollers, and other components for film lamination, bonding, and other processing.

When the film material needs to be changed or a different specification of composite film is required, existing devices often require complex operations, increasing the difficulty of using the equipment and maintenance costs. This limits the applicability and makes it impossible to meet different processing needs. The pressure rollers in existing devices are usually spaced at a fixed interval. However, the thickness and surface characteristics of the composite film often differ during the processing of different film layers or film material types. To address this issue, we have designed a multilayer composite device with a flexible polyimide film insulation layer to provide an alternative technical solution to the above-mentioned technical problems.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1-7 A multilayer composite device for a flexible polyimide film insulation layer includes a vertical support frame 1, multiple detachable rectangular mounting frames 3 are evenly distributed on the top and bottom of one side of the vertical support frame 1, a composite film roll 2 is provided on one side of the rectangular mounting frame 3, and a tension adjustment mechanism is provided on the outside of the composite film roll 2.

[0027] The top and bottom of one end of the vertical support frame 1 are equipped with liftable horizontal connecting plates 6. Both ends of one side of the horizontal connecting plate 6 are equipped with pressure rollers 5, and the other side of the vertical support frame 1 is equipped with a lifting mechanism for lifting the horizontal connecting plate 6.

[0028] The tension adjustment mechanism includes a rectangular mounting plate 13. The rectangular mounting frame 3 has the rectangular mounting plate 13 fixed inside. One end of the rectangular mounting plate 13 is bolted to a third drive motor 14. The output end of the third drive motor 14 is fixed to a first transverse threaded rod 15. The outer side of the first transverse threaded rod 15 is threaded to a transverse sliding plate 16. One side of the transverse sliding plate 16 is rotatably connected to a second oblique rotating rod 17 via a pin. One side of the bottom of the second oblique rotating rod 17 is rotatably connected to a first oblique rotating rod 11 via a pin. The bottom of the first oblique rotating rod 11 is rotatably connected to a tension roller 10 via a bearing.

[0029] The rectangular mounting bracket 3 has a transverse sliding groove inside, and the rectangular mounting plate 13 is located inside the transverse sliding groove. The transverse sliding plate 16 is located inside the transverse sliding groove and is slidably connected to the rectangular mounting bracket 3 through the transverse sliding groove. The transverse sliding groove allows the transverse sliding plate 16 to slide laterally inside the rectangular mounting bracket 3, thereby guiding the transverse sliding trajectory of the transverse sliding plate 16.

[0030] A first drive motor 7 is bolted to the side of the rectangular mounting frame 3 away from the composite film roll 2. A longitudinal rotating column 12 is fixed to the output end of the first drive motor 7. The composite film roll 2 is sleeved on the outside of the longitudinal rotating column 12 and fixedly connected to the longitudinal rotating column 12. The top of the first oblique rotating rod 11 is sleeved on the outside of the longitudinal rotating column 12 and rotatably connected to the longitudinal rotating column 12 through a bearing, so that the first oblique rotating rod 11 can rotate around the longitudinal rotating column 12 as the center. The operation of the first drive motor 7 makes the longitudinal rotating column 12 rotate. The rotation of the longitudinal rotating column 12 makes the composite film roll 2 rotate, so as to facilitate the unwinding of the composite film roll 2.

[0031] When it is necessary to adjust the tension, the third drive motor 14 operates. The operation of the third drive motor 14 causes the first transverse threaded rod 15 to rotate. The rotation of the first transverse threaded rod 15 causes the transverse sliding plate 16 to move laterally inside the rectangular mounting bracket 3. The lateral movement of the transverse sliding plate 16 causes the second oblique rotating rod 17 to drive the first oblique rotating rod 11 to rotate, thereby causing the first oblique rotating rod 11 to rotate around the longitudinal rotating column 12 as the center, thereby allowing the tension to be adjusted.

[0032] By setting multiple detachable rectangular mounting brackets 3, different types of composite film rolls 2 can be flexibly installed according to the specifications and characteristics of different film materials, which improves the adaptability of the equipment and enables it to handle a variety of film materials to meet different production needs. The setting of tension roller 10 makes the tension of composite film roll 2 adjustable when unwinding, ensuring that uniform tension is applied to the film material during the composite process, thereby effectively avoiding the problems of deformation, wrinkles or uneven tension of the film material.

[0033] The lifting mechanism includes a U-shaped mounting plate 8, which is located near the vertical support frame 1 and is fixedly connected to the vertical support frame 1. A second drive motor 9 is bolted to one end of the U-shaped mounting plate 8. A second transverse threaded rod 18 is fixed to the output end of the second drive motor 9. A third transverse threaded rod 19 is provided at the end of the second transverse threaded rod 18 away from the second drive motor 9. The threads of the second transverse threaded rod 18 and the third transverse threaded rod 19 have opposite directions. A transverse sliding block 20 is threaded to the outer side of both the second transverse threaded rod 18 and the third transverse threaded rod 19. An inclined rotating plate 4 is rotatably connected to the bottom of the transverse sliding block 20 through a pin. The bottom of the inclined rotating plate 4 is rotatably connected to the transverse connecting plate 6 through a pin.

[0034] The connection between the second transverse threaded rod 18 and the third transverse threaded rod 19 is rotatably connected to a partition plate via a bearing. The partition plate is fixedly connected to the U-shaped mounting plate 8, thereby making the connection between the second transverse threaded rod 18 and the third transverse threaded rod 19 more stable and preventing the connection between the second transverse threaded rod 18 and the third transverse threaded rod 19 from bending, so that the second transverse threaded rod 18 and the third transverse threaded rod 19 can rotate synchronously better.

[0035] The U-shaped mounting plate 8 has a horizontal guide block fixed inside, and the horizontal sliding block 20 has a horizontal guide groove inside. The U-shaped mounting plate 8 and the horizontal sliding block 20 are slidably connected through the horizontal guide block and the horizontal guide groove. The horizontal guide block and the horizontal guide groove enable the horizontal sliding block 20 to slide horizontally better inside the U-shaped mounting plate 8.

[0036] Here, when it is necessary to adjust the distance between the two transverse connecting plates 6, the operation of the second drive motor 9 enables the second transverse threaded rod 18 and the third transverse threaded rod 19 to rotate. The rotation of the second transverse threaded rod 18 and the third transverse threaded rod 19 enables the transverse sliding block 20 to slide laterally inside the U-shaped mounting plate 8. The sliding of the two transverse sliding blocks 20 enables the transverse connecting plate 6 to be vertically adjusted through the inclined rotating plate 4, thereby adjusting the distance between the two transverse connecting plates 6, and thus adjusting the distance between the pressure rollers 5 at both ends of the two transverse connecting plates 6.

[0037] By adjusting the spacing of the pressure rollers 5, the pressure can be automatically adjusted according to the number of layers of the composite film and the thickness of the material, ensuring uniform pressure. This ensures that each layer of the film receives reasonable and uniform pressure during the multilayer film lamination process, thereby improving the adhesion and overall quality of the composite film.

[0038] Working principle: When tension needs to be adjusted, the third drive motor 14 operates. The operation of the third drive motor 14 causes the first transverse threaded rod 15 to rotate. The rotation of the first transverse threaded rod 15 causes the transverse sliding plate 16 to move laterally inside the rectangular mounting bracket 3. The lateral movement of the transverse sliding plate 16 causes the second oblique rotating rod 17 to drive the first oblique rotating rod 11 to rotate. This allows the first oblique rotating rod 11 to rotate around the longitudinal rotating column 12 as the center, thereby allowing the tension to be adjusted.

[0039] When it is necessary to adjust the distance between the two transverse connecting plates 6, the operation of the second drive motor 9 enables the second transverse threaded rod 18 and the third transverse threaded rod 19 to rotate. The rotation of the second transverse threaded rod 18 and the third transverse threaded rod 19 enables the transverse sliding block 20 to slide laterally inside the U-shaped mounting plate 8. The sliding of the two transverse sliding blocks 20 enables the transverse connecting plates 6 to be vertically adjusted through the inclined rotating plate 4, thereby adjusting the distance between the two transverse connecting plates 6, and thus adjusting the distance between the pressure rollers 5 at both ends of the two transverse connecting plates 6.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
